Synthesis and generation of arbitrary waveforms with ISI components for jitter tolerance

摘要

An Arbitrary Waveform Generator has a controller programmed to generate a sequence of test waveforms using previously-defined waveform data files. The controller generates this series of test waveforms by direct synthesis to cause each waveform to contain a respective different predetermined amount of Rj, Sj and ISI jitter components. In this way, the Arbitrary Waveform Generator produces a sequence of waveforms incorporating varying amounts of ISI to sweep the ISI jitter components from an initial amount of ISI, for example, zero ISI, and continually increment the amount of ISI to a full unit interval of ISI in predetermined increments, for example, 0.1 UI steps.
